I am not picky. Well, maybe I am... I'm not partial to blondes because they seem to be some idealized American form of desire. Plus most of them I have met are dye jobs anyway.
I go through phases (I don't know if it's a biorhythm thing or what) where I'm really crazy about redheads. I fantasize about freckled shoulders and red hair and they drive me nuts when I am in that mode.
But mostly I tend to like dark eyes and dark hair. So mysterious. Love it.
